My understanding is pretty much that only the latest release is supported by
Mozilla. Version 10 is apparently still supported, though, for some reason.
Honestly, Firefox's scheme it started with version 5 is like a parody... hey,
let's constantly upgrade Firefox and inflate the number, no plain old
security fixes or minor versions like every other program, we'll just
constantly throw a new version out every 6 months! Seriously, they might as
well have just ditched the version number. It's not like they actually use it
properly. Seriously, who is going to tell the difference between Firefox 16
and Firefox 8 just by looking at them? It's all security fixes and
performance enhancements.
Remember that Mozilla doesn't have to support version 14 of Firefox for forks
like Abrowser and IceCat to be supported at version 14. I wouldn't worry too
much about it.
